Male.
The body small in size (fig. a), head smaller, shorter than the pronotum. Frons slightly oblique in profile. Vertex narrower, apex acuted (fig. b). The width between eyes is 2 times than the width of frontal costa between antennae. Fastigial foveolae square, the length of fastigial foveolae 3 times as long as width. Lateral margin of frontal ridge parallel above median ocellus and gradually widened toward clypeus, with longitudinal groove. Eyes oval, vertical diameter 1.4 times than transverse diameter and subocular suture. Antennae clubbed, reached the posterior margin of the pronotum, which the widest part is 1.5 times the narrowest part (fig. c). The anterior margin of pronotum straight, posterior margin cambered. Both median carina and lateral carinae distinct, widest of between lateral carinae is 1.8 times than that of narrowest, prozona 1.3 times longer than metazoan (fig. b). The length of mesosternal interspace is 1.1 times than width, metasternal lobes partially connected. Tegmina shorter, reaching 2/3 of the hind femur (fig. a). Precostal area not reaching the median of tegmina. Costal area wider 1.5 times than medial area. Medial area and cubital area equal in width. Anterior and posterior cubitus separate (fig. e). Fore tibia slightly larger than middle tibia, without slender villi. Hind femur with stridulatory pegs in inner lower carinula.

Ovipositor short, apex sharped.
Coloration
